Minimal realization of biquadratic RC-transfer function

The problem of minimal realization of a biquadratic transfer function possessing a pair of complex zeros in the left-half complex plane with maximum gain constant posed earlier by Lin and Siskind has been attempted. For the solution of this problem, a systematic synthesis procedure has been adopted and a relevant realizability theorem has been stated and proved. It has been possible always to realize the theoretical maximum value of gain constant. Furthermore, several examples show that the method requires fewer elements in comparison with other well-known methods.
